In general it seems to me this is a easy way to see the number of connected users/brower, but some WebView systems report a value with -1 or -3.

To get the number of connected workstation user I use "Custom Metric Host (Virtual)|Custom Metric Process (Virtual)|Custom Metric Agent (Virtual)" Metric "Enterprise Manager\|Connections:Number of Workstations" in the past.

I've come across negative value in the past with version 8.x and 9.x. I never got a clear cut answer from CA on what contributes to portraying negative values. I think it's a bug. I don't know if I can dig up a support case I opened up with CA Support but I will try.

I spent some time to test this with Introscope 10.1.0 and I got a "-1" for the Active Browsers Count.

I have seen this issue with 9.6 version at a customer site and appears to be fixed with 9.7 or higher Webview.

The only thing I do in a disordered way, I close my Browser without an logout on the one hand and on the other I open a second Browser to open Webview again and do a logout in both Browser WebView sessions.

After doing this some times I login to the WebView and "WebView:Active Browser Count" is "0" (see the hardcopy).
